04 dakota 4.7 quad cab 4x4 I've replaced all 8 plugs and coils because I had a random misfire on a cold start up if the truck is warmed up it will not miss when you cold start it will misfire but if you give it hard gas it goes away
Any ideas I did do a fuel injector service on it a few months back

 

How's the fuel pressure? I'd probably start there. It should be right around 50 psi.

 

I haven't checked the fuel pressure is it 50 at idle and when I try to start it up on a cold start it takes longer than normal to start
